I am interested in sports (especially baseball and basketball) and video games. My favorite subjects are math, science, and reading. My favorite science topic is Space and the Planets. My least favorite is the Human Body and The Rock Cycle. Finally, I would like to learn more about Space and the Planets this year. (PS I love SPACE!)
EXPERIMENT 1
Problem statement: Which substance can you obtain the most water from, ink, vinegar, or milk?
Hypothesis: If you evaporate the water in vinegar, then you can obtain the most water.
Independent Variable: Type of liquid.
Dependent Variable: Amount of water obtained.
Controlled Variables: Temperature heated, time heating, amount of liquid, machine used to heat the liquid, and type of container.
Research Paper Concentrations Concentration is the amount of solute in a specific amount of liquid or solvent. With the same amount of liquid, with more solute in it, it is more concentrated. With less solute in it, it is less concentrated or diluted. Concentration of Water in Ink, Vinegar, and Milk Ink is mostly water. Vinegar is about 90 to 95 percent water so you can obtain a lot of water from vinegar. Whole cow’s milk is about 87 percent water so you can obtain a lot of water from milk. Physical Properties Physical properties are any properties used to characterize matter and its interactions. Some physical properties of an object are its absorption, area, brittleness, boiling point, color, concentration, density, electric charge, electrical conductivity, emission, flexibility, frequency, location, luminance, magnetic field, mass, melting point, momentum, radiance, solubility, reflectivity, spin, strength, temperature, tension, intensity, length, pressure, thermal conductivity, velocity, viscosity, and volume. Physical Properties of Ink, Vinegar, and Milk Ink is a liquid at room temperature, it can be many different colors, and the density is about 1000 kg/m3. Vinegar is clear, liquid at room temperature, and 1010 kg/m3. Milk is white, liquid at room temperature, and the density is about 1000 kg/m3. Evaporation Evaporation is part of the water cycle and it is when the sun’s heat makes liquid water turn into water vapor which is a gas. Water evaporates at 100 degrees Celsius.
EXPERIMENT 2
Problem statement- Which temperature can you heat vinegar to in order to extract the most water from, 37 degrees C, 48 degrees C, or 60 degrees C?
Hypothesis- If you heat vinegar to 60 degrees C, then you can extract the most water.
Independent variable- Temperature the vinegar is heated to.
Dependent variable- Amount of water extracted.
Controlled variables- Type of liquid, time heating, amount of liquid, machine used to heat the liquid, and type of container.
EXPERIMENT 3
Problem statement- Which amount of vinegar can you heat in order to extract the most water from, 10mL, 15mL, or 20mL?
Hypothesis- If you heat 15mL of vinegar, then you can extract the most water.
Independent variable- Amount of vinegar.
Dependent variable- Amount of water extracted.
Controlled variables- Type of liquid, time heating, temperature heated to, machine used to heat the liquid, and type of container.

Concentrations
Concentration is the amount of solute in a specific amount of liquid or solvent. With the same amount of liquid, with more solute in it, it is more concentrated. With less solute in it, it is less concentrated or diluted.
Concentration of Water in Ink, Vinegar, and Milk
Ink is mostly water. Vinegar is about 90 to 95 percent water so you can obtain a lot of water from vinegar. Whole cow’s milk is about 87 percent water so you can obtain a lot of water from milk.

Physical properties are any properties used to characterize matter and its interactions. Some physical properties of an object are its absorption, area, brittleness, boiling point, color, concentration, density, electric charge, electrical conductivity, emission, flexibility, frequency, location, luminance, magnetic field, mass, melting point, momentum, radiance, solubility, reflectivity, spin, strength, temperature, tension, intensity, length, pressure, thermal conductivity, velocity, viscosity, and volume.
